What is Slag Splashing?
Slag splashing is a technique employed in BOF steelmaking to coat the inner walls of the converter with a thin layer of molten slag. This layer acts as a protective barrier, shielding the refractory lining from the high temperatures and aggressive chemical reactions that occur during the steelmaking process.
Benefits of Slag Splashing:
- Extended Refractory Lining Life: The protective slag layer created by splashing significantly reduces wear and tear on the lining, resulting in increased campaign life and reduced maintenance costs.
- Improved Operational Efficiency: By minimizing refractory lining damage, slag splashing helps to prevent unplanned downtime and production delays, leading to improved overall efficiency.
- Enhanced Steel Quality: The slag layer can also help to improve steel quality by capturing and removing impurities from the molten metal.
The Slag Splashing Process:
- Refining Stage: After the desired carbon content is achieved in the molten steel, the oxygen blowing is stopped, and the furnace is tilted to a specific angle.
- Nitrogen Injection: High-velocity nitrogen gas is injected through a lance inserted into the top opening of the converter.
- Slag Splashing: The nitrogen jet disrupts the molten slag pool, causing droplets of slag to splash onto the exposed refractory lining.
- Solidification: As the furnace cools, the splashed slag droplets solidify on the lining, forming a protective layer.
Choosing the Right Refractories for Slag Splashing:
The success of slag splashing depends on the selection of the appropriate refractory materials. Factors like slag composition, operating temperature, and desired lining life all play a crucial role.
